Busselton Police are questioning a person in relation to an armed robbery which occurred at a Broadwater pharmacy on Monday evening.
A car was searched in West Busselton on Friday in relation to the incident and a person is now assisting police with their inquiries.
On Monday, police reported that a man entered the pharmacy, situated on the corner of Holgate Road and Bussell Highway, around 6pm carrying a large Billabong bag.
Pharmacist manager Michael Hewson said staff and customers were present when the man, armed with a machete, entered the store and demanded drugs from the safe.
“He spoke in a calm way and told us to do what we were told,” he said.
“He was dressed a bit silly and we thought it was a prank. We handed him the drugs and some of our customers watched him running off towards the beach. He must’ve had his getaway planned.
“Thankfully none of the customers or staff were harmed, they’re just a bit shaken.”
Police urge anyone with information to come forward or contact Crime Stoppers on 1800 333 000.
